Chemically nickel oxide nanoparticles (NiONPs) involve the synthesis of toxic products, which restrict their biological applications. Hence, we developed a simple, eco-friendly, and cost-efficient green chemistry method for fabrication NiONPs using fresh leaf broth Rhamnus triquetra (RT). The RT leaves was used as strong reducing, capping, stabilizing agent in formation RT-NiONPs. color change solution from brown to greenish black suggests RT-NiONPs further confirmed by absorption band at...

This study attempts to obtain and test the bioactivities of leaf extracts from a medicinal plant, Geranium wallichianum (GW), when conjugated with zinc oxide nanoparticles (ZnONPs). The integrity extract-conjugated ZnONPs (GW-ZnONPs) was confirmed using various techniques, including Ultraviolet–visible spectroscopy, X-Ray Diffraction, Fourier Transform Infrared Spectroscopy, energy-dispersive spectra (EDS), scanning electron microscopy, transmission Raman spectroscopy. size approximately 18...

A study of x-ray emission from a low energy (1.8?kJ) plasma focus (PF) device powered by 9??F capacitor bank, charged at 20?kV and giving peak discharge current about 175?kA using three different anode shapes with lead insert the tip is reported. Quantrad Si PIN-diodes differential filtering are employed as time-resolved detectors, whereas multipinhole camera suitable absorption filters used for time-integrated analysis. The flux in windows measured function hydrogen filling pressure each...

The National Cancer Institute had projected breast cancer (BC) as one of the topmost prevalent malignancies around globe. In many cases, BC becomes resistant to chemotherapy, radiation and hormonal therapies. Traditional therapies are associated with adverse side effects, drug resistance recurrence. Extensive research work has shown that these dietary phytochemicals (DPs) may exert therapeutic effects by regulating miRNA expression. A large number DPs have been researched regulatory agents...

Abstract The tunable cobalt oxide nanoparticles (CoONPs) are produced due to the phytochemicals present in Rhamnus virgata (RhV) leaf extract which functions as reducing and stabilization agents. synthesis of CoONPs was confirmed using different analytical techniques: UV–Vis spectroscopy, X‐ray diffraction (XRD), scanning electron microscopy (SEM), dynamics light scatterings (DLS), Fourier‐transform infrared spectroscopy (FTIR), energy dispersive X‐ray, Raman analyses. Furthermore, multiple...
